Renntech or aa tune

I have a 2012 x6m with dinan tune but am disappointed with the performance- I am considering either renntech or active autoworker tune now . AA claims more gains and states impressive wheel numbers, Are these numbers accurate? I have akro eve exhaust and will be adding DP with tune- Both renntech and AA offer cattless tunes. Anyone have experience with either company? I went with Dinan originally for warranty but the gains are weak- I dyno'd car and only got about 1/2 their claims gains. I am hoping to get some input before I buy another tune. Thanks
